Project Overview:
This system is installed on the new Milking Barn at the Old Salem Dairy Farm in Olar South Carolina. The progressive farm owners realized the benefits of heating the sterilization water with solar energy made economical and environmental sense. The system uses eight 30 Tube Akotec Heat Pipe Collectors to preheat the sterilization water used in the farm’s state of the art carousel milking equipment. The solar heated water is stored in three Enerworks Super Solar Combi Tanks, with upper and lower heat exchange coils, the solar heated water is then feed into electric water tanks and delivered to the sterilization equipment.
